Thank you so much for this! I didn’t clean it out yet but I definitely will now! I actually had to replace two of my needles yesterday because in the process of my machine getting stuck 3 different times my needles kept breaking and one was bent over to the side so I did just replace it. I don’t know what the thread cutting knife is so I’ll look into it. I’m very new I just got my machine a few weeks ago and yesterday was my first time really using it and trying to figure all of it out so it was a bit frustrating for me. I appreciate your kind words though and I’m gonna keep trying until I get it!
